Google Delivers Android Mobile OS to Developers

Google's Android mobile operating system was made available under an open source license Tuesday morning. Android leapfrogged the release of T-Mobile's G1 smartphone, the first commercial device powered by Android, by one day. According to the Android website, Tuesday's release "offers a full stack: an operating system, middleware, and key mobile applications. Not to be confused with Android's software development kit, the toolset used to build individual applications which was released earlier this year, Tuesday's source code release offers the operating system code -- the actual software which runs the applications.
